Human genetic diversity wouldn't be possible without DNA crossovers in egg and sperm cells. Two studies provide new insights into how crossovers go right -- and wrong, leading to infertility, miscarriages and birth defects.

Researchers have shown that a newly discovered natural antibiotic, teixobactin, could be effective in treating bacterial lung conditions such as tuberculosis and those commonly associated with COVID-19.

Scientists can monitor biomolecular processes in live tissue by noninvasive optical methods, such as fluorescence imaging. However, the fluorescent dyes used for that purpose are often rather unstable, and photobleaching, lack of specificity, and poor pharmacokinetics are recurrent issues. Scientists have now developed a molecular shield that stabilizes near-infrared fluorescent dyes and enhances their functionality.

Scientists at Berkeley Lab's Molecular Foundry have joined forces with a research team at Stanford to aim a gene-targeting, antiviral agent called PAC-MAN against COVID-19.

Today, researchers published the results from the first randomized clinical trial testing hydroxychloroquine for the post-exposure prevention of COVID-19.

In the first few weeks of the lockdown of New Zealand in response to the COVID-19 pandemic, residents reported a slight increase in mental distress but higher levels of confidence in the government, science and the police, as well as greater patriotism, according to new research.

Chronic stress is associated with the pathogenesis of psychological disorders such as depression. A study is the first to identify the role of a neuronal receptor that straddles the intersection between social stress, inflammation, and anxiety in rodent models of stress. Findings suggest the possibility of developing better medications to treat the consequences of chronic stress by limiting inflammatory signaling not just generally, which may not be beneficial in the long run, but to specific brain circuits.

Preliminary observations suggest a high incidence of COVID-19 in stroke patients, including younger patients who were otherwise healthy.

Researchers are working on an entirely new way to detect blood clots, especially in pediatric patients.

Lockdowns implemented across the world due to the COVID-19 pandemic have negatively impacted diet, sleep and physical activity among children with obesity, according to new research.

A new, hair-sprouting dollop of human skin created in the lab might one day help prevent hair loss. An article describes the hairy creation as the first hair-baring human skin organoid made with pluripotent stem cells, or the master cells present during early stages of embryonic development that later turn into specific cell types.

After the US Census Bureau announced that it was changing how it protects the identities of individuals for the 2020 Census, researchers began to evaluate how these changes may affect census data integrity.

Breast cancer survivors in romantic relationships who feel happy and satisfied with their partners may be at lower risk for a host of health problems, new research suggests.

For the first time, researchers have used base editing to restore partial hearing to mice with a recessive mutation in the gene TMC1 that causes complete deafness, the first successful example of genome editing to fix a recessive disease-causing mutation.
